[LARTC] Basic Qdisc : PRIO, pfifo_fast

[LARTC] Basic Qdisc : PRIO, pfifo_fast

[Francesco Schiavello]

Dear   all,

I am starting with Linux Qos mechanism.

I believe that for my needs  the two Qdiscs:
- PRIO
- pfifo_fast

are enough.

In fact I am trying to set up a simple Linux-box 1Lan-1Wan able to
distinguish and give priority to VoIP traffic against IP BE traffic on WAN
interface.

Yet I cannot find any examples concerning these Qdisc (for pfifo_fast I
cannot even find manpages) .

May you help me ?


Thanks in advance for your support.

pfifo_fast:
http://ds9a.nl/lartc/HOWTO//cvs/2.4routing/output/2.4routing-9.html#ss9.2

PRIO:
http://ds9a.nl/lartc/HOWTO//cvs/2.4routing/output/2.4routing-9.html#ss9.5

You can't really configure a lot about pfifo_fast - it is the default.

Regards,

bert

Howdy, I've just happily subscribed to lartc.

It may be worthwhile to add to FAQ that if you have a cbq or some other
queuing discipline attached to the network device, and you want to go back
to pfifo_fast qdisc, you can achieve this by simply deleting the current
qdisc. Then pfifo_fast falls just in place.
I don't know whether this is the right way, but it works for me, and since
it is linux, this makes it the right way ;-)

Kind regards,

It is there already, I think. Will take a look. Thanks.
